I give brainliest! I need help with math .

a) 45

b) 45 mi/hr

c) d = 45t

Step-by-step explanation:

90 mi / 2 hr = 45 mi/hr

135mi / 3hr = 45 mi/hr

225 mi / 5 hr = 45 mi/hr

270 mi / 6 hr = 45 mi/hr

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
